A green analytical chemistry approach for lipid extraction: computation methods in the selection of green solvents as alternative to hexane.

Mari Merce Cascant et al.

Analytical and bioanalytical chemistry, 409(14), 3527-3539 (2017-04-09)

There is a great interest in finding alternatives and green solvents in extraction processes to replace petroleum based solvents. In order to investigate these possibilities, computational methods, as Hansen solubility parameters (HSP) and conductor-like screening model for real solvent (COSMO-RS)

2-methyltetrahydrofuran--lithium hexafluoroarsenate: a superior electrolyte for the secondary lithium electrode.

V R Koch et al.

Science (New York, N.Y.), 204(4392), 499-501 (1979-05-04)

Rechargeable, high energy density lithium batteries require an efficient lithium electrode. Earlier work with electrolytes based on propylene carbonate, methyl acetate, and tetrahydrofuran yielded poor lithium electrode cycling efficiencies because of electrolyte reduction by lithium. Solutions of lithium hexafluoroarsenate in
